Hi:
This is not an ODS or Base Reporting procedure (PRINT, REPORT, TABULATE) question. What you are doing with Web Report Studio and creating batch .srx (SASReport XML) files falls under the category of an Enterprise Intelligence Platform question and is best answered by Tech Support, because your choice of webDAV repository or configuration issues may affect the answer. Or, if you want to create PDF files in the Portal, then you will need to make sure that you generate an HTTP header to indicate to the web client that it is receiving a PDF file.
